GAR-WINDOW cLEsNnn.

I To all whom it may concern: v 7 Be itknown thatI, HERMAN Fnsnnrntn'acitizen of the United States, residing at Hoquiam, in the county of Ghehalis and State of Washington, have invented a new and useful Oar-Window Cleaner, of which the following is a specification.

' -This invention relates to window cleaners, and has for its object to particularly adapt the sainefor remov- ,ing frost, rain water andthe like, from the window of a motor car which is in front of the motor-man.

It isanimportant object of the present invention to mount the cleaning apparatus in such'a relation as to permit of the window being opened without interfering-with the cleaning apparatus, and at the same time to enable the convenient manipulation of the appara-,

' t re for .bringing the same .into operative relation with scribed? shown in the accompanying drawings and' the glass of the window so as to efiectu ally insure the proper cleaning of the glass in every simple and ex 1 peditious manner.

With these and other objects in view, the present invention consists in the combination and ,arrange- 'ment of parts as will be hereinafter more fully departicular'ly pointed out in the appended claims, it being understood that changes in the form, proportion,

" of the'clpims without departing from the spirit or sacrificing any ofthe advantages of the'invention.

In the drawings: Figure l is an outside view of a win dew having the cleaning apparatus of the present invention applied thereto the sheath being broken away to show the apparatus .in its normal inoperative posi- ;.ti,on. Fig. 2 is a similar view showing the apparatus same upon the window. Fig. 3 is an enlarged frag- ."moved out of thg preparatory to working the 3,5.

metallic sheath or housing 4 is mounted in an upright position upon the exterior of the car at one side of the window sash so as not to interfere with the and closing of the latter. This sheath or housing is. closed throughout all sides except that side which is directly towards the window sash,'and will be referred to as the inner open side of the housing. Adjacent the lower edge of the window glass, the frame is pierced by a bushing 5 which is provided at its inner end with an attaching plate 6 pierced by fastenings 7 to rigidly hold the bushing in position. Extending longitudinally through the bushing is an endwise movable rock bar 8 which projects a suitable distance beyond each end of the bushing and is provided upon its outer end opening with a crank arm 9, and upon its inner extremity with a crank handle 10. Loosely embracing the rock bar is a sleeve 11 which is provided upon its oiiter end with a sprocket 12 fixed upon the sleeve, and upon its inner end with acrank handle 13 which is somewhat longer than the crank handle 10. The outer end portion of the-bushing is internally enlarged to form a socket 14 i in which is a'helical spring 15 embracing the sleeve and bearing at one end against the back of the socket, and at its other end against the sprocket 12, whereby the rock bar and the sleeve are normally maintained at their outer limits and are capable of being moved inwardly against the tension of the spring 15.

The outer end of the arm 9 is pierced by a rotatable and endwise movable stub shaftfillfi which is mounted in a rotatable bushing 17 in an" opening in the arm, and is provided with a longitudinal key 18 working in a guideway 19 in the bushing, whereby the bushing andthe stnlo shaft rotate together, while the stub shaft is capable of sliding endwise through the bushing. A helical spring 20 embraces the outer portion of the stub shaft and has its outer end connected to the shaft, as at-21, and its inner end connected to the arm 9, as at 22-," for the purpose of yieldably resisting the rotation of the shaft and to yieldably maintain the latter at its outer limit. A sprocket 23 is mounted upon an intermediateportion of the shaft at the inner side of the arm 9 and is keyed thereon by the key 18. The sprockets l2 and 23 are connected by an endless sprocket chain 24, whereby rotary movement is transferred from the sleeve 11 to the shaft 16. H

The wiper is carried by the inner end of the stub shaft 16 andjncludes telescoped or slidably connected bar members 25 and 26, the inner end of the member 26 being pierced by the stub shaft and held thereon by a set screw27. The members 25 and 26 have a tongue and groove slidable connection, as shown'in Fig. 4, the cross sectional shape of which maybe dovetailed, T-shaped or of other'suitable shape to prevent lateral separation of the members. A rubber, leather or other flexible strip 28 is applied in any suitable 'Inanner to the. member 25 and held in place by means Q cooper of a face plate 29 applied to the outer face of the strip and secured to the member by suitable fastenings, one of which has been shown at m Fig. 4 of the drawings. A similar strip 31 is secured to the member 26 in the same manner as described for the strip 28. The strips 28 and 31 project at the inner edges of the wiper members in order that they may wipe across the window glass and be brought into operative relation thereto. wiper when it is being moved across the window glass, a track is secured to the window sash, said track con sisting of an upper substantially horizontal portion 32, an upright portion 33 at that side of the sash which is opposite the housing 4, and an arcuate portion 34 connecting the members 32 and 33. This portion of the track is carried solely by the window sash, and there is another track section 35 secured to theirarne l in alinement with thenpper track portion 33 and separate therefrom, in .order that the window may be opened and closed without interference by the track. The outer'endoi the wiper member 26 is pro- "vided with a pair-oispaced rollers 36 which enibrace opposite edges of the track and therefore follow the direction of the latter, the track portion 35 being normally embraced by the rollers so as to direct the latter to the track 32' when the cleaning apparatus is moved out of the housing 4. The means for controlling the apparatus include the handles 10 and l3 heroinbefore described, and a cam 37 which is disposed concentrically with respect to the rock bar 8 and has its active edge inclined downwardly from a horizontal shoulder 38 at the top of the cam to a horizontal shoulder 39 at the bottom of the cam. In practice, the apparatus being in an upright position at one side of the window sash, as shown in full lines in Figs. 1, 3 and 4 of the drawings, and the handles in a horizontal position, as best illustrated in Fig. 6, the handle 10 which will be called the offset handle is moved downwardl whereby the handle wipes across the cam 37 ahd draws the rock bar 11 together with the arm 9 and the sleeve 11 inwardly against the tension oi the spring 15. The handle -1O is given a quarter rotation until it strikes the lower shoulder 39 of the cam, and duringthis movement, the arm 9 is swung from its upright position in Fig. 1, tea horizontal position shown in Fig. 2, the wiper being moved out of the housing s and on, to the track 32, the'members oi with the windowglsss.

'Aitsr swinging the handle '10 downwardly, the other handle, which -wilLbe termed the wiping handle, is. then swung downwardly sons to rotate the igleevell and thereby rotate the stub shaft lfi'tlu-ongh the me dium of the sprocket chain 24, whereby the wiperwill be swung downwardly iron: the. outer end of the aunt! as a center, whereby the wiper will clean any accumu lations of frost, rainwater and the like, from. the win-' dow glass. The guide rollers 36 of course followthe For the purpose of guiding the track 32 and thereby telescope the wipe embers so as to lengthen and shorten the wipin device according to the requirements of its changing positions when wiping downwardly across the window.

\ Upon releasing the; handle 13, the tension oi.the

spring 15 will move the rock bar 8 and the sleeve 11 outwardly, and thereby move the wiping members away from the window glass, while: at the same time the crank handles will wipe over the cam 37 and there by rotate the rock bar 8 and the sleeve 11. The back-' '75 ward rotation of the rock bar 8 swingsrthe bar 9 up wardly and back into the sheath or housing 4, while the rotation of the sleeve 11 will rotate the stub shaft 16 through the medium of the chain 24 and thereby swing the cleaning members back into the housing. 8Q. From the foregoing description, i t-will be noted,..

that, with the exception of the track, all of the parts of the present device are mounted independently of the window in order that the latter may be opened andclosed without interference by the cleaning apparatus.

Moreover, the clisaning apparatus is housed and out of the way when not house, and when being operated, it is first moved from a position at one side of the window into a position in engagement with the window glass,

after which the cleaning element is swung down so as to scrape across the glass and thereby remove frost andthe like therefrom in a very simple and expeditious manner.
